meteorology of 1897.

quired for a barometer will purchase a good set of thermome- 
ters and a rain gage which, systematically observed, will yield 
useful climatic data. 
SUB-STATIONS. 
The observations at Cheyenne Wells and at Rocky Ford 
are not given in detail, but are summarised in tables 3 and 4. 
The conditions of exposure are not so good as at Fort Collins. 
The averages and the reduction to determine the dew point 
and relative humidity from the observations are computed at the' 
home station at Fort Collins. For a portion of the year the' 
wet and dry bulb thermometers observed at the Cheyenne- 
Wells station were obtained from other sources than through the- 
home station, and it was subsequently found that the ther- 
mometers were in error, and the corresponding relative humidi- 
dities a,nd dew points are incorrect.
